Worked out of the box without any problems on Linux
Easy to have in your bag for when required. Drivers were easy to find on the website and it works fine.
Wanting to connect and control a solar inverter with Solar Assistant and Home Assistant, I needed an RS485 converter. This one was easy to attach and just worked. Add cable, plug in and it is done.
As described, no complaints.
Bought this to use with Home Assistant and my solar inverter. Great device, hasn’t needed a reboot so far. The quality is a nice touch.
